This study was fulfilled to evaluate the durability of VOCs for different sampling methods. The sampling methods widely used to collect atmospheric VOCs are Canister method (EPA method TO-141, Absorbtion tube method (EPA method TO-17), and Tedlar-bag method, and those methods are used in this study. The samples were analyzed after 0, 1, 3, 7, 15, 30 days to figure out the durability of components while keeping under low temperature (4℃) and room temperature (about 20 ℃). Each sample collected by above sampling method was analyzed by high resolution gas chromatography (GC) with flame ionization detector (FID). The test results were shown that the compounds in canisters and absorbtion tubs were stable, but the ones in tedlar-bags were not stable. Heavy components such as Toluene, m/p-Xylene in absorbtion tubes were kept their stability for a long time longer than the ones in canisters. However, the reducing rates of heavy components in canisters were not bigger than those of Tedlar-bags. The VOCs sample collected and stored in tedlar-bag are unstable for analysis, even after a days. As a result of this study, it is found that Canister method and Absorbtion tube method are reliable for collection and storage for a variety of ozone precursors compared to Tedlar-bag method. It is strongly recommended that the samples collected using Tedlar-bag need to be analysed shortly after sampling.

A field study was conducted during the summer time of 2002 to determine compositions of volatile organic compounds (VOCs) emitted from vehicles and to develop source emission profiles that is applied to CMB model to estimate the source contribution of certain area. Source emission profile is widely used for the estimation of source contribution by the chemical mass balance model and have to be developed applicable fur the large1 area of estimation. This study was aimed to develop source emission profile and estimation of source contribution of VOCs after application of the chemical mass balance (CMB) receptor model. After considering the emission inventory and other research results for the VOCs in Seoul, Korea, the sources like vehicle emission(tunnel), gas station (gasoline, diesel), solvent usage (painting operation, dry cleaning, graphic att), and gas fuels were selected for the major VOCs sources. Furthermore, ambient air samples were simultanceusly collected from 09:00 to 11:00 for four days at eight different official air quality monitoring sites as receptors in Seoul during summer of 2001. Source samples were collected by canisters, and then about seventy volatile organic compounds were analyzed by gas chromatography with flame ionization detector (GC/FID). Based on both the developed source profiles and the database of the receptors, CMB model was intensively applied to estimate mass contribution of VOCs sources. Examining the source profile from the vehicle, the portion of alkanes of VOCs was highest, and then the portion of aromatics such toluene, m/p-xylene were followed In case of gas fuel, they have their own components: the content of butane. propane. ethane was higher than any other component according tn the fuel usage. The average of the source apportionment on VOCs for 8 sites showed that the major sources were vehicle emission and gas fuels. me vehicle emission source was revealed as having the highest contribution with an average of 49.6% and followed by solvent with 21.3%, gas fuel with 16.1%, gasoline with 13.1%.

One of the Musty and earthy smell compounds in raw water is generally attributed to 2-methylisoborneol (2-MIB). It is well known that activated carbon and oxidants such as O_3, ClO_2 are effective ways to control 2-MIB. In isotherm equilibrium experiments, 2-MIB in distilled water was much more adsorbed to the activated carbon(A/C) than raw water containing dissolved organic carbon (DOC). The Freundlich constants(k) of distilled water and raw water were 3.36 and 0.049, and 1/n values were 0.80 and 0.42, respectively. The 2-MIB residual rate were Y = e^(0.55_x)~ e^(-0.54_x) with Ozone(O_3) dose by 5 minutes contact time at the 241 and 353 ng/L initial concentrations. The 2-MIB residual rate were Y = e^(-0.32_X)~ e^(-0.35_X) with Chlorine dioxide(ClO_2) dose by 15 minutes contact time at the 89 and 249 ng/L initial concentrations. 2-MIB was decreased from 1911 ng/L to 569ng/L by post-ozonation(70%removal efficiency) and removal efficiencies of 2-MIB by the following 4 kinds Granular Activated Carbon(GAC) process such as coal base, coconut base, wood base and zeolite+carbon base were 95.8, 89.5, 88.4, and 93.7% respectively.

This study is prepared to introduce design quality improvement measures by the trend and cause analysis of design changes which have been made during operations of construction project for power plant. In this study, two types of analysis tool have mainly taken for the use of the improvement measures. One tool is the trend analysis to identify which action should be taken to cut down design changes. This is also useful to monitor whether project participant's endeavour for the action taken is effective or not, to the project performance and design quality improvement. The other is the cause analysis, by using cause and effect diagram, which is useful to identify main causes of the design changes and to establish the measures to reduce recurrence of the design changes.

Immunogenotyping using gene rearrangement analysis has emerged as a precise laboratory aid in the diagnosis and classification of malignant Iymphoid neoplasms. The lineage and clonality of the malignant Iymphoid neoplasms can be identified by the demonstration of rearrangements of antigen receptor genes of the immunoglobulin and T-cell receptor genes. The analysis of the gene rearrangements on the malignant Iymphoid neoplasms are also useful as a sensitive unique clonal markers to detect early recurrence in patients with malignant Iymphoid neoplasms after treatment. To analyze the sensitivity and specificity of gene rearrangements in the diagnosis of malignant Iymphoid neoplasms. 24 cases of malignat Iymphoma were examined by Southern blot hybridization using CTβ-T cell receptor β chain gene-DNA probe and JH-immunoglobulin heavy chain gene-DNA probe. The results of the immunogenotypings using Southern blot hybridization disclosed high correlation between the immunophenotyping using immunohistochemical stain with monoclonal antibodies (B-cell Iymphoma 84.2%. T-cell Iymphoma 75% ). The analysis of the gene rearrangement of the angioimmunoblastic lymphadenopathy(AILD) and unclassifiable Iymphoma using immunohistochemical stain could resolve the monoclonality and lineage . Rearranged bands to the CTβDNA probe were observed in one case out of 2 cases of AILD. One case of unclassifiable Iymphoma showed rearranged bands to the CTβ DNA probe. There were no rearrangements in reactive follicular Iymphoid hyperplasia and paracortical Iymphoid hyperplasia. In conclusion, DNA gene rearrangement study should be applied to differentiate the clonality and cell lineage in the malignant Iymphoma with indistinctive immunophenotype.
